NOTES:
-
Individual results may vary.
-
Chipper: approx. 400HP, Diesel fuel consumption:
approx. 30 gal/hr. Diesel Fuel at $4.50/gal
-
It is assumed that chips cannot be reasonably
sold for beneficial re-use.
-
Chipping process and chip handling produces
large amounts of particulate matter (PM) in the
form of wood dust that can cause serious illness
in exposed workers. Wood dust is a proven
carcinogenic (cancer-causing). Chipping losses,
mostly in form of wood dust, are approx. 2% or 2
tons in this example. Only 98 tons of wood chips
are deposited into the landfill.
-
Air Curtain Burner residual is 3 tons of ash, hauled by 1
truck, but is usually land-applied on site;
Chipper residual yields no weight reduction, but
does provide significant volume reduction.
In this example, waste is hauled by at least 12
trucks, each carrying approximately 22 cubic
yards or 5 – 6 tons.
-
Direct hauling of land clearing wood waste to
landfill will require approximately 25 trucks.
-
The S-220 is a medium size above ground
refractory walled firebox. Larger and
smaller models and trench burners are
also available. See
